FURUNO TB-1 Field Time Sync Generator & Accessory Kit
FURUNO TB-1 Field Time Sync Generator is a portable GNSS reference signal generator for RF system maintenance and R&D in the field. The TB-1 (main unit only) provides one pulse per second (1PPS) and a 10MHz reference frequency, both synchronized with Coordinated Universal Time (UTC), which can be used in digital broadcast, 5G, and V2X system field testing for time synchronization and frequency measurement purposes.
The FURUNO TB-1 Field Time Sync Generator can do the same work as an atomic clock to measure the synchronization delay of mobile base stations. The frequency output of TB-1 is as stable as an atomic oscillator. It can be used as a reference signal for frequency checks of rubidium oscillators used in broadcasting stations and for field reception surveys. The TB-1 can be used for experiments in moving vehicles as it has a small form factor and is easy to handle. The device is suitable for frequency and delay measurements in V2X system development and for synchronizing multiple sensors with the UTC.
The internal GNSS receiver of the TB-1 includes countermeasures against GNSS vulnerabilities such as multipath, jamming, spoofing, and GNSS signal loss. The GNSS receiver also includes the Dynamic Satellite Selection™ algorithm, which minimizes deterioration of time synchronization performance by choosing only the high-quality satellite signals. The TB-1 GNSS satellite reception can be checked and managed on an Android™ smartphone or tablet via the FURUNO TB-1 app.
TB-1 (Main Unit Only) and TB-1KIT are separate products and should be purchased together.
